Abstract: The soil pollution characteristics of typical pollution industries in Shanghai were studied from the following aspects: basic physical property, pH, heavy metal pollution. The potential ecological hazards of heavy metal pollution were assessed by Las Hakanson Index. The results indicated that soil of typical pollution industries had been affected by former manufacturing process. The heavy metal pollution distributed in those factories, such as printing and dyeing factories, battery manufacturers, electric plating factories and oil refinery plants. The risk level of heavy metal Hg and Cd were relatively high, and followed by Pb、Cr、Zn、Ni and As. Countermeasures against the soil pollution of typical polluting industries are suggested.

Key words: typical polluting industry, soil pollution, heavy metal, potential ecological risk assessment, typical polluting industry, soil pollution, heavy metal
